Courtly dance (6)
I believe the answer is:
minuet
'courtly dance' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for minuet that I've seen before include "Stately court dance" , "Stately old dance, takes only a minute" , "Stately C 18 dance" , "18th-century dance" , "Slow, graceful dance" .)
